rnnss FIXTURE.

Application filed September- 24, 1923. Serial No. 664,482.

To all whom t may concer/LI.'

Be it knownthat I, IRA A. WEAVER, a citi- Zen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Press Fixtures, of which the following is a specification.

My present invention pertains to means for facilitating the performance of certain types of work such as riveting, punching, etc., and aims to provide simple and eifective means for holding the body to be acted upon by the riveting or other tool in correct and proper relation to the latter during the execution of its functions.

The new and improved appliance may be used in association with a press of any approved lstyle or it may be employed with hand implements such as a heavy hammer or the like.

The novel device is of simple conformation, it is relatively inexpensive to produce, and it assures an ease and correct carrying out of the intended operation because the work and toolA or too-ls are always maintained in proper relation one to the other.

To enable those acquainted. with this art to fully understand the invention and its several accruing advantages, I have illustrated a desirable and preferred embodiment of the invention in the accompanying drawing forming a part of this specification and throughout the several views of which like reference characters refer to the same parts. p

In this drawing Figure 1 is a fragmentary perspective view of a press equipped with the new device;

Figure 2 is a vertical cross-section online 2-2 of Figure 2, the parts being viewed in the direction indicated by the arrows, and

Figure 8 is a fragmentary, perspective view on a reduced scale illustrating the riveting of a gear of the differential mechapending upon the direction of rotation ofV such wheel, thewheel of course having a large mechanical advantage inthe operation of such shaft by reason of the screw 'connection.

The new -app-liance'comprises a portable base-block 14 Vresting on the top edges of the supporting-member y11 at 15 and having an intermediate part 16 (Figure 2) extending Vdown between the plates andpreventing lateral displacementof the block, thelatter having'two, spaced, horizontallegs or extensions, 17, 17 v of appropriateL shape in cross-section and supplied at their ends with short, downwardly-projecting lugs or ears 18, 18 positioned outside of the plates 11, 11 precluding sidewise movement of such legs,

whereby the block, of which theselegs really constitute a part, is effectively held in place against dislodgment.

Element 14 has an upwardly-curved arm or bracket -19 integral therewith, such part terminating in a portion 21ahaving a bearing to receive a vertically-disposed, riveting, punching or other tool 22 capable of sliding movement in such bearing to perform its work. i

Directly beneath this tool,the;member1t has a hole extended vertically therethrough designedto removably or detachably receive a die-block 23 arranged to accommodate dies for dierent sizes of rivets or to receive a perforated or apertured die so that the punch may be used for punching'holes as well as setting rivets and performing other operations.

In order that the work, for instance, the differential ring-gear of an automobile, may be properly supported on the die 23, the ex` tensions 17, 17 of the base-block are each supplied with a plurality of threaded holes 24 any one or more of which is designed to adjustablyreceive one or more threaded supports or studs 25 on which the work is intended to rest. f

Owing to the fact that the punch or other tool has a bearing in the saine integral member which supports the work and the die proper, correct alignment of the punch and die is assured at all times which is essential to an exact and correct performance of the tools action. l

Inasmuch as the base casting is open at the bottom between the extensions or legsl and is openat one end of the latter, the

differential housing containing the ring-gear as commonly used in automobiles can be readily and easily slid into place from the side.

The Work having been placed in position and supported on the die and studs, the punch is caused to descend and head over the rivet or perform Whatever other work is required of it, misalignment of the punch and die, as Well as inisplacement of Work, being impossible if the Work is properlyi positioned in the first place.

As the rivet projects a considerable dis'- tance through, the punch must Work straight down in order to upset it and lill the hole completely.

if one attempts to upset a rivet cold With a hammer, the end is battered up and bruised and the rivet is not properly ,de- Vformed to completely fill the hole,

It has been found diiiicult also in the average garage, Where appliances of tnis kind are particularly adapted for use, to properly heat the rivets and set them `With a hammer or tool Without injury to the gear.

As this device is made in a single piece casting, the punch-holder is always in line and good Work with inexperienced help can be accomplished With it, Without incurring the disadvantages in the ordinary garage specified above. t

The invention is not limited and restricted to the exact and precise details of structure presented since these may be modified Within comparatively Wide limits Without departure from the heart and essence of the invention and without the sacrifice of any or' its substantial benefits and advantages.

I claim:

l. A portable appliance of the character described adapted for use on a press, comprising in combination, a base adapted to rest on the bed of the press having horizontal extensions spaced apart and separated at their ends remote from said base leaving a vertical unobstructed opening between said extensions, an arm upstanding from said base and having a portion overlying the latter, a punch-bearing in said portion, means on said base in alignment with said punchbearing to receive a complementary die, and

adjustable abutments on said extensions to lsupport the Work to be acted upon by the punch and die.

2. A port-able appliance of the character described adapted for use on a press, comprising in combination a base adapted to rest on the bedoi` the press having horizontal extensions spaced apart and separated at their ends remote from said base leaving a vertical unobstructed opening between said extensions, an arm upstanding from said base and having a portion overlying the lat ter, a punch-bearing in said portion, said base having a die-receiving recess in register With said punch-bearing, said extensions having a plurality of threaded sockets in their top faces on opposite sides of said opening, and .threaded Work-supporting studs in said sockets.

ln Witness whereof lhave hereunto set my hand and seal.
